Nephrons are the functional units of the kidneys, responsible for filtering blood and producing urine. There are two main types of nephrons:
- Cortical Nephrons: Located mostly in the outer part of the kidney (cortex).
- Juxtamedullary Nephrons: Located near the boundary between the cortex and the inner part (medulla) of the kidney.
Juxtamedullary nephrons play a crucial role in concentrating urine, which helps the body retain water and maintain a proper balance of salts and other substances.
Nephron swelling refers to an abnormal enlargement or swelling of the nephrons. This condition can disrupt the kidney’s ability to filter blood effectively, leading to various health issues. Swelling can result from different factors, including infections, toxins, or underlying diseases affecting the kidneys.
Pathophysiology
Pathophysiology is the study of how normal physiological processes are altered by disease.
Structure
- Nephrons: Each kidney contains about one million nephrons. Juxtamedullary nephrons have long loops of Henle that extend deep into the medulla.
- Loop of Henle: Essential for concentrating urine. In juxtamedullary nephrons, this loop is longer, allowing for greater concentration of urine.
Blood Supply
- Renal Artery: Supplies blood to the kidneys.
- Afferent Arterioles: Branch from the renal artery to supply blood to each nephron.
- Efferent Arterioles: Carry blood away from the nephron after filtration.
- Peritubular Capillaries: Surround the nephron and facilitate exchange between blood and kidney tissue.
Nerve Supply
- Sympathetic Nervous System: Regulates blood flow and filtration rate in the kidneys.
- Autonomic Nervous System: Influences kidney function, including urine production and electrolyte balance.
Types of Nephron Swelling
Nephron swelling can be categorized based on its underlying cause:
- Inflammatory Swelling: Caused by infections or autoimmune diseases.
- Toxic Swelling: Resulting from exposure to harmful substances or medications.
- Ischemic Swelling: Due to reduced blood flow to the kidneys.
- Hydropic Swelling: Caused by an imbalance of electrolytes and fluids.
